注意css设置：

其他版本的JS代码：

function Marquee(opt) {
    let MyMarhq;
    clearInterval(MyMarhq);
    let tagName = $('.' + opt.name);
    let tblTop = 0;
    let speedhq = opt.speed || 20;
    let outerHeight = tagName.outerHeight();
    let children_Height = tagName.children().height()
    tagName.scrollTop(0)
    if (children_Height > outerHeight) {
        tagName.children().html(tagName.children().html() + tagName.children().html())

        function Marqueehq() {
            if (parseInt(tagName.scrollTop()) >= children_Height) {
                tblTop = 0;
            } else {
                tblTop += 1;
            }
            tagName.scrollTop(tblTop)
        }

        MyMarhq = setInterval(Marqueehq, speedhq);
        tagName.hover(function () {
            clearInterval(MyMarhq);
        }, function () {
            clearInterval(MyMarhq);
            MyMarhq = setInterval(Marqueehq, speedhq);
        })
    }
